The Cayman Islands experience relatively good weather all year round. The average daily temperature varies little, and Cayman tends to experience comfortably cool winter nights and hot summer days most days.
December - April are the coolest times to visit with trade winds keeping the climate temperate (this is also peak season for visitors). January and February are the coolest months with daytime highs in the upper 70's to low 80's and nighttime lows in the mid 60's to low 70's. Beautiful sea breezes keep the temperature at an ideal both during the day and in the evening. Many visitors choose to travel in the winter as the temperature is usually consistent and pleasant (plus they are often escaping a very cold winter somewhere else)!
May - November is the rainy season; however, rain tends to come in short, sharp bursts and clears relatively quickly. Summer temperatures peak in July and August, with daytime highs in the upper 80's to low 90's and nighttime lows in the low 80's. Cayman summer months can experience high humidity, but sea breezes help cool the evenings down. Many visitors choose to travel during the rainy season as prices are cheaper, and the beaches are less crowded.
